Analysis of the spectral efficiency of the basic standards of cellular communication: methodological instructions for laboratory exercises on the course "Systems" by author B. A. Aksenova is an indispensable source of knowledge for students, graduate students and specialists in the field of telecommunications and radio communication . With the rapid development of cellular technology, understanding spectral efficiency is becoming a key aspect for future engineers and researchers. This work offers a deep and systematic approach to the study of current standards such as GSM, UMTS, LTE and 5G, which makes it especially relevant for those who want to be at the forefront in this dynamic field. The book not only outlines the theoretical foundations, but also provides the reader with practical methodological instructions that will help in conducting laboratory exercises. Aksenov masterfully combines theory with practice, which allows students not only to assimilate information, but also to apply it in practice. This makes the book especially valuable for those who prefer active training and want to get real skills in working with modern communication systems. The topics raised in the book cover a wide range of issues related to the analysis and evaluation of spectral efficiency. The reader will be able to learn about the methods of measurement and analysis, as well as the influence of various factors on the effectiveness of the use of the radio frequency spectrum. This knowledge is crucial in light of the increasing load on the networks and the need to optimize the spectrum to improve the quality of communication. The book also touches on issues related to the future development of cellular technologies and standards, which makes it especially interesting for those who want to anticipate trends in this area. Aksenov's style is distinguished by clarity and accessibility of presentation, which allows even beginners in the field of telecommunications to easily assimilate complex concepts. His previous works, such as Radio Fundamentals and Modern Data Transfer Technologies, have also been recognized for their practical focus and relevance. In this book, the author continues this tradition, offering readers not only theoretical knowledge, but also practical skills that they will be able to apply in their professional activities. The book will be of interest not only to students and graduate students, but also to practitioners working in the field of cellular communication, as well as to anyone who is interested in modern technologies and their development. It is suitable for readers aged 18 years and older who want to deepen their knowledge in the field of telecommunications and radio communication.
